I want to add aprox. another 25-30 lbs of LS instead of buying it could I go to the beach and dig a few buckets full of dirt? I live near the Gulf of Mexico if that makes any diffrence.
YA, but probably not the best idea. There's bound to be some dieoff, and who knows what's mixed in the sand/water. If you don something like this I definitely wouldnt do too much at one time, and certainly far less than 25lbs.
